What is Ozone Water Treatment?

Ozone water treatment is a powerful and eco-friendly method of purifying water, effectively removing contaminants and improving its overall quality. As awareness of the importance of clean water grows, ozone water treatment has become increasingly popular for both residential and commercial applications.

Ozone water treatment is a process that is used to purify, disinfect, and improve the quality of water using ozone gas, which plays an important role in the atmosphere as well.

How exactly does ozone water treatment improve the quality of your water?

The Science Behind Ozone Water Treatment Systems: Oxygen Atoms

So, how does ozone water treatment work? Ozone (O3) is a highly reactive gas consisting of three oxygen atoms that is leveraged in electrolytic and chemical reactions. It is formed when oxygen molecules (O2) are exposed to ultraviolet (UV) light or an electrical discharge, such as lightning. In water treatment, ozone is generated by passing air or pure oxygen through a high-voltage electrical field. This process creates ozone, which is then dissolved into the water to be treated.

When ozone comes into contact with water contaminants, it oxidizes and destroys them. This powerful oxidation process effectively breaks down organic and inorganic impurities, leaving behind only oxygen (O2) and harmless byproducts.

Advantages of Ozone Gas Water Treatment

There are a number of reasons why you should consider taking advantage of ozone water treatment. This treatment process offers several advantages over traditional water treatment methods. Some of the top examples include:

Powerful Disinfection

Ozone is a powerful oxidant, making it extremely effective at destroying bacteria, viruses, and other microorganisms. In fact, ozone has been found to be more effective at inactivating waterborne pathogens than chlorine, with fewer harmful byproducts.

Removes a Wide Range of Contaminants

Ozone water treatment can eliminate a broad spectrum of contaminants, including organic compounds, heavy metals, and pesticides. It is also effective at neutralizing taste and odor issues caused by substances like hydrogen sulfide and algae.

No Harmful Byproducts

Unlike chlorination, which can produce harmful disinfection byproducts, such as trihalomethanes (THMs) and haloacetic acids (HAAs), ozone water treatment does not produce any long-lasting harmful byproducts. Ozone breaks down into oxygen, leaving no chemical residue in the treated water.


Ozone is generated on-site, eliminating the need for hazardous chemical storage and transportation. As a result, ozone water treatment is an environmentally friendly option for purifying water.

Ozone Water Treatment Applications

Ozone water treatment has a wide range of applications in various industries and settings:

Drinking Water Treatment

Ozone water treatment is widely used in municipal water treatment plants to purify drinking water. It effectively removes contaminants, enhances water quality, and provides a reliable disinfection barrier against waterborne pathogens.

Wastewater Treatment

In wastewater treatment, ozone is used to disinfect and break down pollutants before the water is discharged back into the environment. Ozone’s powerful oxidation properties make it an effective solution for reducing the environmental impact of wastewater.

Swimming Pool and Spa Treatment

Ozone water treatment is an excellent alternative to traditional chlorine-based disinfection for swimming pools and spas. It provides effective sanitation without the unpleasant side effects of chlorine, such as eye and skin irritation, and strong odors.

Aquaculture and Aquarium Treatment

Ozone water treatment is used in aquaculture and aquarium systems to maintain optimal water quality. It helps control harmful bacteria and parasites, reduces the buildup of organic waste, and improves water clarity.

Food and Beverage Industry

In the food and beverage industry, ozone water treatment is used for sanitizing equipment, surfaces, and produce. Ozone’s powerful disinfection properties ensure that harmful microorganisms are

effectively eliminated, helping to maintain high standards of hygiene and food safety.

Cooling Towers

Ozone water treatment can be used in cooling towers to control the growth of bacteria, algae, and other microorganisms. This helps to maintain the efficiency of the cooling system, reduces the need for chemical biocides, and minimizes the risk of Legionella outbreaks.

Laundry Facilities

Ozone can be used in commercial laundry facilities to improve the cleaning and disinfecting process. Ozone-treated water can effectively remove stains and kill bacteria, reducing the need for hot water and harsh chemicals, which results in energy savings and a reduced environmental impact.

Ozone Water Treatment Equipment and Systems

There are various types of ozone water treatment equipment and systems available, depending on the specific application and requirements:

DROP Ozone Complete

Ozone Generators

Ozone generators are the key component in any ozone water treatment system. They produce ozone by passing air or oxygen through an electrical field. Ozone generators vary in size and capacity, depending on the intended application and required ozone output.

Ozone Injection and Mixing Systems

To effectively treat water with ozone, it must be properly dissolved and mixed into the water. This can be achieved using venturi injectors, diffusers, or static mixers. The choice of injection and mixing system depends on the water flow rate, ozone concentration, and water quality.

Ozone Monitoring and Control Systems

Ozone monitoring and control systems are essential for ensuring the effectiveness and safety of the ozone water treatment process. They measure the ozone concentration in the treated water and adjust the ozone output accordingly to maintain the desired level of disinfection.

Ozone Destruct Units

Ozone destruct units are used to safely convert any excess ozone back into oxygen before it is released into the atmosphere. This prevents the release of ozone gas, which can be harmful to humans and the environment.

It is important for you to think carefully about which option is best for your needs, and to reach out to a professional who can help you.

Factors to Consider When Implementing Ozone Water Treatment

Given that there are so many options available, how can you select the right one for your needs? When considering ozone water treatment for your specific application, there are several factors to take into account. They include:

  • Water Quality: The quality of the water being treated will determine the required ozone dosage and contact time. High levels of contaminants or organic matter may require a higher ozone concentration to achieve the desired level of disinfection.
  • System Design: The design of the ozone water treatment system must be tailored to the specific application and requirements. This includes selecting the appropriate ozone generator, injection and mixing systems, and monitoring and control systems.
  • Maintenance and Operation: Regular maintenance and monitoring are essential to ensure the safe and effective operation of the ozone water treatment system. This includes checking the ozone generator for wear and tear, maintaining the injection and mixing systems, and calibrating the ozone monitoring and control systems.

Keep in mind that ozone is not the only way you can improve the quality of your water.

Use Water Softeners To Help

If you need help stripping excess calcium and magnesium minerals from your water supply as well, you need to put water softeners to work for you. Water softeners replace excess calcium and magnesium with sodium instead, helping you protect the life of your plumbing appliances. Water softeners can also help your water feel better against your skin, particularly when you shower. At DROP, we can help you find the right water softeners for your needs.
